IUL vs. 401(k): Which Comes First for Retirement Savings?

If your employer offers a 401(k) match, contribute enough to get the full match before you put a dollar into an indexed universal life (IUL) policy. The match is money you only receive by saving in the plan, and the 401(k) gives you tax breaks and investing without the insurance charges built into a policy. An IUL can still earn a place later, but as life insurance first and a savings tool second.

This guide compares the two on limits, taxes, fees and access to your money. If you are new to IUL, start with what indexed universal life insurance is.

What is the difference between an IUL and a 401(k)?

A 401(k) is a workplace retirement plan; an IUL is a permanent life insurance policy with a cash value account. They are built for different jobs.

The IRS describes a 401(k) as a feature of a qualified plan that lets employees put part of their wages into individual accounts. Employers can add money too. An IUL is a contract with an insurance company. Your premium pays for a death benefit and funds a cash value that earns interest based on a stock index, limited by a cap and usually protected by a floor.

Why should you get your 401(k) match first?

Because an employer match is extra pay that no insurance policy can replicate. If you skip it, that money is gone.

The IRS 401(k) page notes that employers can contribute to employees' accounts. How much depends on your plan, so check your summary plan description or ask HR for the match formula.

Watch the vesting schedule. According to the IRS guidance on vesting, your own salary deferrals are always 100% yours, but 401(k) plans can require you to work a set number of years before employer contributions fully belong to you. If you might change jobs soon, find out how much of the match you would keep.

What are the 401(k) contribution limits for 2026?

For 2026, you can defer up to $24,500 of your pay into a 401(k), up from $23,500 in 2025. That is according to the IRS announcement of 2026 limits (IR-2025-111).

• Age 50 and older: an extra $8,000 catch-up, for a total of $32,500.
• Ages 60 to 63: a higher catch-up of $11,250 instead of $8,000.
• Same limits apply to 403(b) plans, most governmental 457 plans and the federal Thrift Savings Plan.

The IRS also sets a separate overall limit on total contributions to your account, which includes employer money. Limits change most years, so check the IRS contribution limits page before you set your deferral.

An IUL has no IRS contribution limit of this kind. But if you pay in too much too fast, the policy can fail the "7-pay test" in 26 U.S.C. § 7702A and become a modified endowment contract (MEC), which changes how withdrawals and loans are taxed.

How are an IUL and a 401(k) taxed?

A traditional 401(k) gives you a tax break now and taxes you later; an IUL gives no break now but can offer tax advantages later if it is managed well.

401(k). The IRS says elective deferrals are excluded from your taxable income, except Roth deferrals. Distributions, including earnings, are taxable when you take them, except qualified distributions from a designated Roth account. Taking money out before age 59 and a half generally adds an extra 10% tax unless an exception applies, according to the IRS list of exceptions. One exception covers leaving your job during or after the year you turn 55.

IUL. Premiums come from after-tax money; the IRS says you can't deduct premiums you pay on your life insurance. Cash value growth is not taxed while it stays in the policy. For a policy that is not a MEC, 26 U.S.C. § 72(e) generally taxes withdrawals only to the extent they exceed what you paid in, and does not treat policy loans as taxable distributions. The death benefit is generally not taxable income to your beneficiary, according to the IRS.

Those advantages have limits:

• If you surrender the policy, IRS Publication 525 says you must include in income any proceeds that are more than your cost in the policy.
• If the policy is a MEC, section 72 treats loans and withdrawals as taxable gains first, with an extra 10% tax on the taxable part before age 59 and a half in most cases.
• Ask the insurer and a tax professional how a lapse with an unpaid loan would be taxed before you borrow.

For a broader look, see is life insurance taxable.

Which costs more, an IUL or a 401(k)?

An IUL usually costs more, because part of every premium pays for life insurance and policy expenses before anything is credited to cash value.

Fees matter in a 401(k) too. The Department of Labor's guide to 401(k) fees shows that for a worker with 35 years to retirement and a $25,000 balance, assuming 7% average returns and no further contributions, a 1 percentage point difference in fees and expenses would reduce the account balance at retirement by 28 percent. You can see your plan's fees in its annual fee disclosure.

In an IUL, charges come straight out of your cash value each month. The New York Department of Financial Services warns that universal life internal charges "can increase every year," and that payments plus cash value must be enough to cover ongoing policy expenses or the policy will lapse.

How easy is it to get money out of each one?

Neither is ideal for short-term needs, but they restrict access in different ways.

A 401(k) generally taxes withdrawals and may add the 10% extra tax before age 59 and a half. Some plans allow loans or hardship withdrawals; your plan documents spell out what is allowed. Required minimum distributions generally start at age 73, though the IRS RMD FAQs note that workers in a plan can often delay until they retire, and designated Roth accounts have no RMDs while the owner is alive.

An IUL lets you withdraw or borrow against cash value at any age, with no required distributions. The catches:

1. Cash value is low in the early years while charges are highest.
2. FINRA notes that permanent policies often include early surrender charges.
3. Loans accrue interest, and unpaid loans reduce the death benefit.
4. Borrowing too much can drain the cash value and cause a lapse.

We explain how policy loans work as income in IUL for retirement income.

When does an IUL make sense alongside a 401(k)?

An IUL can make sense when you need life insurance that lasts for life and have extra money to fund it well for many years. It rarely makes sense instead of a 401(k) match.

It may be worth comparing if you:

• Already capture your full employer match and save steadily for retirement
• Need a death benefit that lasts past the years a term policy would cover
• Have income that can pay premiums well above the minimum for decades
• Want some tax-advantaged cash value you can reach before 59 and a half
• Will review an in-force illustration every year and add money if needed

It is usually a poor fit if you are behind on the match, carry high-interest debt, or might need to stop premiums in a few years.
